The changes of optical transmission and of the index of refraction were studied in flash evaporated Ge-Sb-S layers. Photobleaching, photodarkening and photoinduced crystallization were observed depending on the composition of layers. The effects are qualitatively explained using the idea of photoinduced atoms and/or chemical bonds rearrangement.
